Structure of a stackable bucket

ABSTRACT

A stackable bucket structure has a hollow body. The top end of the body is protruded upward with a neck part with an opening. The bottom end of the body has a concave accommodating part. The accommodating part has an inner sidewall edge and a supporting surface. The diameter of the inner sidewall of the accommodating part is slightly larger than the outer diameter of the neck part, so that the bucket can use its accommodating part to connect to the neck part of another bucket. When the accommodating part of one bucket connects to the neck part of another bucket, the supporting surface of the accommodating part urges against the top end of he neck part.

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to a bucket structure and, in particular, to a stackable bucket structure.

2. Related Art

When storing usual buckets, one often encounters the trouble that they cannot be stacked up because there is no connection structure between them. It is thus an important issue to be solved. Based on many years of practical experience, the inventor comes up with the idea of the invention.

SUMMARY OF THE INVENTION

An objective of the invention is to provide a stackable bucket structure that facilitates bucket stacking. It can effectively reduce the space occupied by the stored buckets.

To achieve the above objective, the disclosed stackable bucket structure has a hollow body that protrudes upward with a neck part having an opening on the top end thereof and has a concave accommodating part at the bottom end thereof The accommodating part has an inner sidewall edge and a supporting surface. The diameter of the inner sidewall edge is slightly larger than the outer diameter of the neck part, so that the bucket can use its accommodating part to connect to the neck part of another bucket. When the accommodating part and the neck part are connected, the supporting surface of the accommodating part urges against the top end of the neck part of another bucket.

Another embodiment of the disclosed stackable bucket structure has a hollow body that protrudes upward with a neck part having an opening on the top end thereof and has a concave accommodating part at the bottom end thereof. The neck part has a cover, and the accommodating part has an inner sidewall edge and a supporting surface. The inner diameter and shape of the inner sidewall edge of the accommodating part match with the outer diameter and shape of the cover for the bucket to use its accommodating part to connect to the cover of the neck part of another bucket. When the accommodating part and the neck part are connected the supporting surface of the accommodating part urges against the top surface of the cover of the neck part of another bucket.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

Please refer to FIGS. 1 and 2 for a first embodiment of the invention. The disclosed stackable bucket structure in this embodiment has a hollow body 11 that protrudes upward with a neck part 13 having an opening 12 on the top end thereof. The neck part 13 is formed with a connecting section 131 toward its top end. The hollow body 11 has a concave accommodating part 14 of a predetermined depth at the bottom end thereof. The accommodating part 14 has an inner sidewall edge 141 and a supporting surface 142. A shrinking limiting section 143 is formed between the inner sidewall edge 141 and the supporting surface 142. The inner diameter and shape of the inner sidewall edge 141 of the accommodating part 14 match with the outer diameter and shape of the neck part 13, so that the bucket can use its accommodating part 14 to connect to the neck part 13 of another bucket.

Please refer to FIGS. 3 and 4. The inner diameter and shape of the inner sidewall edge 141 of the accommodating part 14 match with the outer diameter and shape of the neck part 13, so that the bucket can use its accommodating part 14 to connect to the neck part 13 of another bucket. Therefore, the accommodating part 14 of the bucket 10 can be conveniently connected to the neck part 13 b of another bucket 20. The buckets can thus be stacked together. When the accommodating part 14 of one bucket 10 and the neck part 13 b of another bucket 20 are connected, the supporting surface 142 of the accommodating part 14 urges against the top end of the neck part 13 b of another bucket 20. The limiting section 143 of the accommodating part 14 of the bucket 10 urges against the connecting section 131 b of the neck part 13 b of the other bucket 20. This ensures the stability of the stacked buckets.

Please refer to FIGS. 5 and 6 for a second embodiment of the invention. The bucket structure in this embodiment has a hollow body 31 that protrudes upward with a neck part 33 having an opening 32 on the top end thereof. The neck part 33 has a cover 34 for sealing the opening 32 of the neck part 33. The cover 34 is formed with a connecting section 341 toward the top end. The body 31 has a concave accommodating part 35 of a predetermined depth at the bottom end thereof. The accommodating part 35 has an inner sidewall edge 351 and a supporting surface 352. A shrinking limiting section 353.is formed between the inner sidewall edge 351 and supporting surface 352. The inner diameter and shape of the inner sidewall edge 351 of the accommodating part 35 match with the outer diameter and shape of the cover 34, so that the bucket can use its accommodating part 35 to connect to the cover 34 of the neck part 33 of another bucket.

Please refer to FIGS. 7 and 8. The inner diameter and shape of the inner sidewall edge 351 of the accommodating part 35 match with the outer diameter and shape of the cover 34, so that the bucket 30 can use its accommodating part 35 to connect to the cover 34 of the neck part 33 b of another bucket 40. When the accommodating part 35 of the bucket 30 and the cover 34 b of the neck part 33 b of the other bucket 40 are connected, the supporting surface 352 of the accommodating part 35 of the bucket 30 urges against the top surface of the cover 34 b of the neck part 33 b of the other bucket 40. The limiting section 353 of the accommodating part 35 of the bucket 30 urges against the connecting section 341 b of the cover 34 b on the neck part 33 b of the other bucket 40. Using such a structure, this embodiment can achieve very good stability when stacking the buckets together.

Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to people skilled in the art. Therefore, it is contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
